tunica externaformerly known as "tunica adventitia" and is composed of
connective tissue. Inside this layer is the
tunica media, or
media, which is made up of
smooth musclecells and elastic tissue. The innermost layer, which is in direct contact with the flow of blood is the
tunica intima, commonly called the
intima. This layer is made up of mainly
endothelial cells. The hollow internal cavity in which the blood flows is called the
Elastic Artery, Muscular Artery, Arteriole
tunica externa, tunica media, and tunica interna
The brachiocephalic artery, the left common carotid artery, and the left subclavian artery
Three
The three layers are Tunica Intima, Tunica Media, Tunica Externa
Arteries actually have 5 layers, it is the veins that have 3. Arteries have: -the Outer coat -Elastic layer -Middle coat (thin) -Another elastic layer -Endothelium
capillaries
Blood vessels are composed of three layers of tissue: tunica externa, tunica media, and tunica interna. The middle layer, tunica media, is composed of smooth muscle and is thickest in arteries because they need to accommodate the higher pressures created by the heart's pumping action which distributes blood throughout the body.

The walls of the arteries are very thick in fact artery walls consist of three cell layers.

smooth muscle
Arterial walls are made up of three layers: the tunica intima, tunica media, and tunica externa. The tunica media is the thickest layer in arteries.
Veins are more likely than arteries to expand or dilate if blood volume or pressure increases, because they consist of only one layer of tissue; this is in contrast to arteries, in which there are three layers.
the three blood vessels are the Veins capillaries Arteries the arteries.
